bd2420f8fa libstdc++: Add comparison operators to sequence containers 
Some more C++20 changes from P1614R2, "The Mothership has Landed".

This implements <=> for sequence containers (and the __normal_iterator
and _Pointer_adapter class templates).

	* include/bits/forward_list.h (forward_list): Define operator<=> and
	remove redundant comparison operators for C++20.
	* include/bits/stl_bvector.h (vector<bool, Alloc>): Likewise.
	* include/bits/stl_deque.h (deque): Likewise.
	* include/bits/stl_iterator.h (__normal_iterator): Likewise.
	* include/bits/stl_list.h (list): Likewise.
	* include/bits/stl_vector.h (vector): Likewise.

	* include/debug/vector (__gnu_debug::vector): Likewise.
	* include/ext/pointer.h (__gnu_cxx::_Pointer_adapter): Define
	operator<=> for C++20.
	* testsuite/23_containers/deque/operators/cmp_c++20.cc: New test.

1a7886386c libstdc++: Fix <ext/pointer.h> incompatibilities with C++20 
The equality operators for _ExtPtr_allocator are defined as non-const
member functions, which causes ambiguities in C++20 due to the
synthesized operator!= candidates. They should always have been const.

The _Pointer_adapter class template has both value_type and element_type
members, which makes readable_traits<_Pointer_adapter<T>> ambiguous. The
intended workaround is to add a specialization of readable_traits.

	* include/ext/extptr_allocator.h (_ExtPtr_allocator::operator==)
	(_ExtPtr_allocator::operator!=): Add missing const qualifiers.
	* include/ext/pointer.h (readable_traits<_Pointer_adapter<S>>): Add
	partial specialization to disambiguate the two constrained
	specializations.
